Tolcapone is used together with other medicines (carbidopa and levodopa) to treat symptoms of Parkinson's disease, such as stiffness, tremors, muscle spasms, and poor muscle control. Tolcapone increases levels of levodopa in the body. Tolcapone is usually given to people who are already taking carbidopa and levodopa but have not had successful treatment of symptoms. Tolcapone may also be used for other purposes not listed in this medication guide.
